A904 for 360 Magnum

OK, so this would be a 360 Magnum crate engine and a new transmission, so pre-'68 comment I don't think applies (unless I'm misinterpreting it). TCI tells me that this A904 will bolt up to 360 Magnum and small block LA, same pattern. Re the FI, I will be using aftermarket FuelTech throttle body injection, same as on my slant, so only needs reprogramming for v8. Regarding "TCI's transmissions" aren't they just rebuilding OEM A904's to their specs? I am using the '67 style, single post, neutral safety switch on my slant's A904, so I'd want to use the same one on the new tranny.
